nvidia binary driver works only sporadically with the default kernel ("GPU has fallen off the bus" in dmesg since linux 3.10). However, nvidia 331.20 does load and work properly with linux-ckAUR kernel (linux-ck-ivybridge 3.12.5-1 from Unofficial user repositories/Repo-ck) if boot parameter rcutree.rcu_idle_gp_delay=2 is given. See [1].

TouchPad seen as standard PS/2 mouse, not Synaptics apparently.BIOS says touchscreen is enabled but unsure of what drivers would work.OSD and some Fn buttons work - brightness, volume control, battery check.
